First X-ray detection of a colliding-wind binary beyond the Milky Way
02-16-2007 · European Space Agency (ESA)Imagine two stars with winds so powerful that they eject an Earth's worth of material roughly once every month. Next, imagine those two winds colliding head-on. Such titanic collisions produce multimillion-degree gas, which radiates brilliantly in X-rays. Astronomers have conclusively identified the X-rays from about two-dozen of these systems in our Milky Way. But they have never seen one outside our galaxy — until now.

- Vast cloud of antimatter traced to binary stars
01-09-2008 · EurekAlert!
Four years of observations from the European Space Agency's Integral (INTErnational Gamma-Ray Astrophysics Laboratory) satellite may have cleared up one of the most vexing mysteries in our Milky Way: the origin of a giant cloud of antimatter surrounding the galactic center.

- Possible progenitor of special supernova type detected
02-13-2008 · EurekAlert!
Using data from NASA's Chandra X-ray Observatory, scientists have reported the possible detection of a binary star system that was later destroyed in a supernova explosion. The new method they used provides great future promise for finding the detailed origin of these important cosmic events.

- Discovering teenage galaxies
11-27-2007 · EurekAlert!
Staring for the equivalent of every night for two weeks at the same little patch of sky with ESO's Very Large Telescope, an international team of astronomers has found the extremely faint light from teenage galaxies billions of light years away. These galaxies, which the research team believes are the building blocks of normal galaxies like our Milky Way, had eluded detection for three decades, despite intensive searches.

- Beyond the book: Software automates access to brain atlases
12-14-2006 · EurekAlert!
USC computer scientists have found a cheap, quick and copyright-respecting way to turn existing print brain atlases into multimedia resources. The software, now available in an experimental beta version for free download, is a robust and user-friendly interface that works on all the most popular computer operating systems.

- Test for visual acuity could aid detection, rehabilitation of AMD
10-29-2007 · EurekAlert!
A computer-based method for evaluating the eye’s ability to distinguish object details and shape in patients with age-related macular degeneration (AMD) could provide a more accurate way to assess the effectiveness of eye surgery or vision rehabilitation interventions with devices and training, according to a Canadian study. The computer method could also vary low-, medium- and high-contrast illumination targets for testing spatial vision, which the authors say might be useful for early detection of AMD.

- New population of faint protogalaxies discovered
11-28-2007 · EurekAlert!
Carnegie astronomers have found a new population of faint protogalaxies by taking the most sensitive spectroscopic survey ever of a time when the universe was only 15 percent of its present age. These objects are the probable building blocks of galaxies today, including our own Milky Way. The discovery substantiates a popular theory of galaxy formation.
